control usb led

[askalottaqs]

hello everyone!

is it possible to control the led (on/off) when attached through the usb port through python?

I need to write a little code to play around with the lights, i really have no clue where to start addressing the issue, and would love any kind of guidance.

Thanks a lot

ok so far ive reached the fact that usb gets continuous power from the computer, even when turned off, therefore i cant really control the input of electricity to it. what i can actually do is add a controller which ill send the command to, and from there it will switch it on or off. the only problem is that i have no clue how to build a controller, or which to buy that i would actually be able to control. I'm sorry about how wide this information is but i just dont have a clue where to start with this.

thanks again

if it is any comfort, what you are trying to accomplish is quite vague too me as well...

1. you have somekind of usb device, with somekind of lamp? And somehow you want to turn this lamp on and off? and you want to do this from a high-level language like python?

You can buy an Arduino prototyping circuit board built for this very sort of application.
